ATTORNEY! United States Patent Office' 3,150,464 METAL PANELS FOR BUILDING SIDING WITH JOINT FDR LOCK UP OR PILE N INSTAL- LATION Selwyn Shmitt, Milwaukee, Wis., assignor to Lumaside, Inc., Milwaukee, Wis., a corporation of Wisconsin Filed July 18, 1961, Ser. No. 124,831 3 Claims. (Cl. 50-218) This invention relates to building siding and especially to top and bottom margins of panels for such siding to provide for alternative pile on or lock up joints between the respective courses of such panels.

Panels for fabricated siding have heretofore provided various types of joint and appearance features. The joint details are frequently complicated and considerable time is consumed in applying the panels to building structures. Design details are usually conventional in that they provide faithful simulation of conventional wood lapsiding or clapboards, but if it is desired that a particular installation show a heavy shadow line at the joint due to a simulated thick lap siding, a separate supply of metal or plastic panels for such an installation must be separately stocked as contrasted with panels simulating thinner lap siding with lighter shadow lines. Thus, according to prior panel constructions, a separate inventory of each design and each joint variation has been necessary.

Objects of this invention are to provide a siding panel of metal or other suitable material so shaped as to lend itself to alternative styles of application; to provide a siding panel that is simple in design of the marginal joint configuration so as to make possible in a single design, produced by a single set of tooling and dies, for one product to meet all installation requirements; and to simplify inventory problems since one type of siding panel can be supplied for alternative methods of installation and application.

Another object is to provide in a single design of panel and panel margin configuration more than one possibility of panel joint interengagement so that a product of one set of tooling and dies and in one warehouse product of such tooling and dies to make possible alternatively the laying up of wall siding of various ultimate architectural results.

In the drawings:

FIGURE 1 is a perspective view of a siding panel embodying this invention.

FIGURE 2 is an enlarged fragmentary elevational view of related siding panels as applied to a wall surface.

FIGURE 3 is a vertical sectional view taken at line 3-3 of FIGURE 2 and showing the pile on relationship of applied siding panels.

FIGURE 4 is a view similar to FIGURE 3 but showing the lock up relationship of siding panels.

The panel of this invention, indicated as 19, is shown in FIGURES 3 and 4 mounted on a structure 12, such as a wall of wood or of the well-known sheeting materials such as Celotex. Panel comprises a sheet 14 of metal or suitable material of a length desired and of a width to permit forming of a panel to the dimensions desired. Many special configurations of the top and bottom margins have heretofore been provided, as for instance those shown in the US. patent to Lockwood No. 2,853,163; but they have been limited to a single lock up or pile on method of use whereas these margins according to the instant invention are formed as follows:

The upper margin 16 of sheet 14 is provided with anchor tabs 18 spaced at intervals along margin 16 and which are formed out of sheet 14 by the well-known process of piercing and forming. Holes 20 accommodate suitable nails 22 which are driven into the structure 12 when applying the siding.

3,15%,454 .Patented Sept. 29, 1964 Upper margin 16 is formed outwardly from the plane of structure 12 and coextensively with sheet 14 in the form of a first downwardly-open groove 24 and an adjacent upwardly-open channel 26 and terminates in an upwardly-directed lip 28.

Sheet 14 extends divergently downwardly with respect to the structure 12 and is provided with a lower, overhang or drip edge 30, which terminates in an upwardlyextending wall 32 and a bead 34. A downwardlyextending lip 36 defines a second downwardly-open groove 38. Wall 32, bead 34 and lip 36 are so proportioned that they will provide a frictional fit in groove 24 when assembled as in FIG. 4, thereby providing a tight rattle-proof construction.

Reference to FIGS. 3 and 4 will indicate that the gist of this invention is embraced by a siding panel that lends itself to two examples of wall treatment. Namely, to an application that has a deep overhang as shown in FIG. 3, and one having a shallow overhang as shown in FIG. 4. Thus the invention provides a means of simplifying storage, inventory and shipping.

The application of the panel of this invention will now be explained:

Structure 12 is prepared in the usual manner, is conventional and need not be further described. An initial panel 10 is leveled horizontally at the bottom of structure 12 and secured to the structure by nails 22 through tabs 18, as shown in FIGS. 2, 3 and 4. If it is desired to apply the panels with a wide overhang, also called pile on as shown in FIG. 3, each successive panel after the application of the initial panel, is applied so that lip 36 rests in channel 26. The upper margin 16 is then fastened to structure 12, as described with reference to the initial panel.

If the siding is to be applied with a shallow overhang also called lock-up, as shown in FIG. 4, each successive panel after the initial panel, is applied so that bead 34 is inserted upwardly into groove 24. The upper margin of the panel is then fastened to the structure 12 as previously set forth.

It will be obvious that the applicant has provided a single siding panel that lends itself to two alternative applications; shallow or deep overhang.

Having now described my invention and in what manner the same may be used, what I claim as new and desire to protect by Letters Patent of the United States ls:

l. A siding panel, comprising a sheet portion having an upper and a lower edge, and an inner and outer side, means on said upper edge adapted to receive fastening means, said upper edge comprising an outwardly extending portion having a cross-section defining a first downwardly open groove adjacent said sheet and an upwardly open channel adjoining said first groove and terminating in an upwardly directed lip, said lower edge having a portion extending toward said inner side and terminating in an upwardly extending bead having a cross-sectional width sutficient to receive said first downwardly open groove, and having a downwardly directed lip defining a downwardly open second groove having a cross-sectional width sufficient to receive said upwardly directed lip, said upwardly open channel having a crosssectional width sufiicient to receive said downwardly directed lip.

2. A siding panel having a substantially plane surface having bottom and top margins and inner and outer sides, said top margin having an upwardly open groove spaced outwardly from said outer side in a direction approximately normal to said surface, and a downwardly open groove between said outer side and said upwardly open groove, said bottom margin having a downwardly open groove spaced inwardly from said inner side, and a wider upwardly open groove between said inner side and said downwardly open groove spaced from said inner side, said wider upwardly open groove having a configuration approximately right angular in cross-section.

3. A siding construction in combination with a wall structure, comprising a series of adjoining longitudinal siding panels including upper marginal means for securing the panels to the structure, each panel comprising a sheet portion having an upper and a lower edge, said upper edge comprising an outwardly extending portion having a cross section defining a first downwardly open groove adjacent said sheet and an upwardly open channel adjacent said first groove terminating in an upwardly directed lip, said lower edge having a portion extending toward said structure and terminating in an upwardly extending bead defining a downwardly open second groove, the outer side of said bead comprising a downwardly directed lip, each successive panel positioned selectively with said upwardly extending bead inserted in said first groove in the previously applied panel for a shallow overhang or with said downwardly directed lip engaged in said upwardly open channel for a deep overhang.
